97 gp gt cat replacement - 09/10/07 06:29 PM
i was thinking my cat might be stopped up but dont know a way to test it i was thinking of getting a pipe to replace it with and drive it for 200 miles and see if there was a diffeence in gas mileage and performance what i was needing to know is if there is a place i can order a pipe to just bolt on in place of the cat and also if the car will run ok without the cat on it anymore
